IMPROVEMENT IN VALVES. FOR PUMPS.

The Schedule referred to in these Letters-Patent and making part of the same.

To all whom it 'may concern;

Be it known that I, JAuEs CLAYTON, of Brooklyn, in the county of Kings, and State of New York, have invented a new and improved Valve for Pumps `and other purposes; and I do hereby declare that the following` is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which'- 5 Figure l represents a vertical section of a puppetvalve for a pump constructed according to my iml provement. l

lgigure 2 is a view of the' valve, without the seat; an(

-Figure 3 is a plan of the improvedvalve, with its cap removed. t

'Similar letters of referencepindicate corresponding parts in the several figures.

This yinvention consists in a novel construction of valves for pumps and other. purposes, with movable caps and Ways through their heads, whereby provision is made for the passage of a greater quantity of water or other ilnid than through a valve of the ordinal'y construction, the size of the valve and stroke of the 'piston beidg equal. l

In order that others may be better enabled to understand the construction and operation ofv my inven tion, I will proceed toy describe it, with reference to the drawings- A is the valve-seat, having iitted to it the valve B, which is constructed after` the usual manner of puppet-valve, except that besides the usual water-ways c c, in its sides below the head, it has. additional waterways a a through the head itself.v E

These water-ways are covered by a cap, C, which consists'of a disk, having in its centre ahole which fits easily to a stem,re, projecting upward from the head of the valve, and tting to a seat on the top of 'the head, in substantiallythe samemanner as an ordinary valve ts to its seat. y

A light spring, b, is coiled around the stem e, and secured in such manner above the oa'p C'as to, exert a tendency to close it.

When, by the action of the pump-piston, the water is drawn or forced through the valve, the cap C is.

Vlifted from its seat, on the head of the valve B, at the same time the said valve B is lifted from its seat A,

and thejwater passes through the water-ways aga, in the valve-head, as well as through the'water-ways c c, in the sides of the valve; and .when the direction of the pump piston is reversed, thereby causing the pressv nre onthe opposite side of the valve to predominate,

the cap O drops to its' seat on the head of the valve,

assisted bythe coiled spring b, thereby covering the water-ways a a, While the valve B closes Yinto it-srseat A, thereby closing the water-ways c c.

The movable cap and additional water-'ways inthe head provide for a more copious passage of water than is practicable, when only the usual water-ways c c are provided in the valve. A K

This improvement is applicable to valves forsteanr and all other fluids, and two or more caps may be applied, one upon another, to one valve, in which case all the caps but the top one will have ways a athrongh them to be opened and closed by the cap next above.v The spring b, operating on the upper c'ap, or valve, causes it to close quickly, and prevents the loss ol' water that would result were they dependent upon gravity alone for such action.

What I claim as my invention, and desire to secure by Letters Patent, is Y The arrangement of the cap C and spring b, on the stem c of the valve B, in conibinationwith the seat A, substantially as shown and described.

JAMES CLAYTON.
